I have a 27" iMac 5K running Mac OS X 10.10.2 and iPhoto 9.6.1 when looking at your photos you can bring them up but they are very small. I know that the resolution of the 5K monitor is very high and you can zoom. However my wife doesn't like the way it looks and we don't want to zoom every picture. Any ideas on how to change the appearance? Is it just something that has to do with the photo resolution. Thanks for your help.
